My friend is having some issues with some plants of his. He said they are 10 days old now. To start off with he had them floating on top of the water in star foam. Today I Helped him put them in the medium, But noticed that all 4 plants look different. 1 has been strong since day 2, 1 has been short and stayed short. 1 has been growing decent BUT now is starting to loose some health, and then the last one is the one he is most worried about. The leaves are starting to curl under and turn a super dark green color. I am thinking it might be due to over watering since he had them floating, But we changed the setup this morning and it has not livened up any. They where all in the same water. Any Ideas? This is the stronger one, which is starting to curl. This is the one that is not looking too good. This is the 2nd strongest one, but as you can see the starting leaves are burnt. And last but not least the midget one.
